For those of you (like me) who appreciate an online quiz now and again, here's one that made me pretty happy. The Sierra Club's How Green Is Your Bike? quiz asks a few questions on your biking experience and habits and then tells you how green you are with your riding.
I was pleased to get a 95 out of 100 - knocks came for having an aluminum bike (steel is the most easily repairable frame, but aluminum is a close second, apparently) and being more likely to stop at a convenience store than to eat off the land while biking. Of course, I'm not sure what they'd want me to eat on the streets of Columbus... but there you are.
People, not speed.
